in reply to Passing subroutine as argument between packages

Valid usage this function: $FooConfig->important_func, but reference return &PackageName:: before

I'm not sure I understand what your problem is.  As it seems, you appear to have figured out that the correct way to call the method would be $FooConfig->important_func( ... ). So where/when are you getting the &PackageName:: you don't want?

Upon rethinking, maybe you want something like this 

    my $ref = sub { $FooConfig->important_func( '1' ) };

which would 'bind' the object instance and the method parameter to the coderef, so that you could call it later on as $ref->().

    Thank you for you answer,

    I want ask you about one more thing: in this method, how pass eventually arguments for subroutine $FooConfig->important_func?

    I checked $ref()->('a' ), $ref()('a'), $ref->( 'a' ), $ref->()('a'), $ref->()->('a') or like this, and didn't work.

      Given:

      my $ref = sub { $FooConfig->important_func( '1', @_ ) };

      ... then you can write:

      $ref->( 'more', $args, %here );

      ... though be cautious and understand how the function reference passes its arguments to the inner function.

        Simple @_ is solution - now works fine!
